The 74-year-old star who has been married three times says she and her have discovered "true intimacy"
She said: "When I had my knee replaced just over two and a half years ago, I found a lover. His name is Richard Perry, he is 70 and he is a music producer".
"When I moved in with him I was still using crutches; we haven't been apart since".
"The only thing I have never known is true intimacy with a man. I absolutely wanted to discover that before dying. It has happened with Richard, I feel totally secure with him. Often, when we make love, I see him as he was 30 years ago.
"At 74, I have never had such a fulfilling sex life. When I was young I had so many inhibitions - I didn't know what I desired."
Jane admits she often changed herself to please the men in her life, but blames her father Henry Fonda for her problems.
She told Britain's HELLO! magazine: "I was always a courageous woman, capable of confronting governments, but not men. I was a chameleon, the woman men wanted me to be.
"I don't want to make a cheap analysis, but when you have, like I did, a father incapable of showing emotion, who spends his life telling you that one will love you if you aren't perfect, it leaves scars."
